Historians have used AI to restore lost verses of Gilgamesh,, read carbonized papyrus scrolls sealed for millennia, and fill in gaps in 2,000-year-old Greek inscriptions.

What ancient codes will AI crack next?

The gimlet has been maligned for decades, says Ty Caudle, our beverage director, as a result of artificial ingredients and rushed preparations. The Interval recipe has corrected those deficiencies by using navy strength gin infused with lime oil and slowly filtered over three days. The resulting lime cordial is stirred (rather than shaken) to create a perfect pearlescent finish.

Our Navy Gimlet was just named best in the city by , and included on this exceptional list which maps the best and most storied bars in the city. It’s an honor to be included.

"I saw my first Whole Earth Catalog in a bookstore. I opened it up and it was like, ‘This is for me. He's talking to me. This is exactly everything that I'm interested in.'"

Kevin Kelly, Long Now board member and founding editor of Wired magazine, talks to Substack about long-term thinking, technoptimism, and how he helped shape the early internet. Plus, it’s filmed in a beautiful location if we do say so ourselves.

The radical optimist on starting Wired, stories from the early internet, originating 1,000 True Fans, and why the only way to steer technology is to use it

Need a new excuse to visit The Interval this month? May’s Short Here is the Velvet Fedora, described as “the whiskey cousin of a margarita,” and a riff on the Ninth Ward.

The Ninth Ward is traditionally a spicy, citrus-forward cocktail made with bourbon, and named after the eastside district of New Orleans. John swapped the bourbon for the floral, velvety notes of Japanese whisky, creating something refreshing and exceptionally smooth.

Ingredients:
Nikka Days Japanese whiskey
Velvet Falernum
Elderflower liqueur
Creole bitters
Elderflower salted rim

On the menu through the end of May.
